Mexico’s tourism officials have unveiled the second phase of their “Live It To Believe It!” campaign. The first phase focused on some relatively unusual destinations and sights in Mexico. The second phase is based on the nation’s extraordinarily varied gastronomy. “Eat Here to Believe It!” is our suggested shorthand.

Mexican cuisine has taken the world by storm in recent years and Mexico is rapidly becoming one of the best destinations in Latin America for food-related travel. Promotional videos (sadly, no longer available on Youtube) highlight how regional variations in cuisine across Mexico mean that a vacation in Mexico can be like visiting several different countries in a single trip.

In addition to items such as tequila and mescal enjoying international protection and recognition via their denomination-of-origin status, in 2010 UNESCO added the indigenous regional cuisine of Michoacán to its “Intangible Cultural Heritage of Humanity” list.

Quoting from the UNESCO site:

Traditional Mexican cuisine is a comprehensive cultural model comprising farming, ritual practices, age-old skills, culinary techniques and ancestral community customs and manners. It is made possible by collective participation in the entire traditional food chain: from planting and harvesting to cooking and eating. The basis of the system is founded on corn, beans and chili; unique farming methods such as milpas (rotating swidden fields of corn and other crops) and chinampas (man-made farming islets in lake areas); cooking processes such as nixtamalization (lime-hulling maize, which increases its nutritional value); and singular utensils including grinding stones and stone mortars.

Native ingredients such as varieties of tomatoes, squashes, avocados, cocoa and vanilla augment the basic staples. Mexican cuisine is elaborate and symbol-laden, with everyday tortillas and tamales, both made of corn, forming an integral part of Day of the Dead offerings.

Collectives of female cooks and other practitioners devoted to raising crops and traditional cuisine are found in the State of Michoacán and across Mexico. Their knowledge and techniques express community identity, reinforce social bonds, and build stronger local, regional and national identities. Those efforts in Michoacán also underline the importance of traditional cuisine as a means of sustainable development.

¡Buen provecho!

The abduction and presumed murder of 43 students in the state of Guerrero

 Mexico's geography in the Press  Comments Off on The abduction and presumed murder of 43 students in the state of Guerrero
Nov 182014
 

The disappearance several weeks ago, and presumed murder, of 43 students from a teachers’ college in Ayotzinapa in the state of Guerrero has shocked the nation and sent shock-waves around the world. The isolated mountainous parts of the state of Guerrero have long been home to some of the worst violence and most severe poverty in Mexico. The students went missing in the town of Iguala on 26 September 2014.

We appreciate that many of our readers will already be well informed about recent events, but hope that the following summary, with its links to English-language sources, will be useful.

Mexico’s attorney general has announced that a drug cartel, operating in tandem with the mayor of Iguala and the mayor’s wife, had kidnapped and killed the students, before burning their bodies beyond recognition and dumping the remains in plastic bags in a river. According to some versions, local police were not only aware of the events, but complicit in them.

mexico-kidnapping-horizontal-gallerySoon after the disappearance of the students, several mass graves were located on the outskirts of Iguala, but none of the remains has yet been positively identified as belonging to any of the missing students. However, the remains did include the body of a Roman Catholic priest from Uganda, missing since May 2014. John Ssenyondo, who had been serving in the region since 2010, was allegedly abducted by armed men for refusing to baptize the daughter of a suspected narco.

Earlier this month, security experts searching the landfill site near the town of Cocula (where gang members allegedly killed and burned the students) found rubbish bags with human remains. The charred remains have been sent to a specialized laboratory in Innsbruck, Austria, for testing, but results will not be known for several weeks.

A judge in Guerrero has since charged the city’s former mayor, Jose Luis Abarca, with being the mastermind behind the students’ disappearance, and of responsibility for the murder of six people killed in clashes between the trainees, police and masked gunmen on the night of 26 September 2014. The government has detained more than 70 people in connection with the disappearance of the students. Maria de los Angeles Piñeda, the wife of the local mayor is alleged to be the head of the area’s major drug cartel. Abarca and his wife have both been arrested. The small town of Iguala, site of the murders, installed a new mayor, Luis Mazon, after the incumbent was arrested for ordering the massacre, but he resigned in disgust after only a few hours in office, to be replaced by Silviano Mendiola.

Bloody demonstrations are taking place across the country, threatening tourism and denting the carefully-crafted public relations image of President Enrique Peña Nieto.

In Chilpancingo, the state capital of Guerrero, 600 protestors set fire to cars, a congressional office and the city hall.

The tourist resort of Acapulco has also been the scene of demonstrations. For a short time protestors prevented flights from taking off from the city’s airport, and have also blocked highways. The hotel occupancy rates plummeted to 20% for a time, before beginning to rise again in recent days.

In Mexico City, protestors set fire to one of the wooden doors of the Presidential Palace on the zocalo, Mexico City’s main square. The president has an office in the building but was leading a trade mission to China at the time.

Speaking to Fox News Latino recently, a student leader from the Ayotzinapa school said that, “It’s a national movement that’s launching. People are really upset in Mexico. It’s a movement for all citizens that is sparking protests across the country. That’s what happening now. We’re sending caravans to Chihuahua, Zacatecas, all the states from north to south. It’s family members [of the victims] and student-teachers.” The students also accept fire-bombings as a valid form of political expression.

Reactions in the USA have been mixed. For example, see:

The Huichol (Wixárika) People’s fight against multinational mining companies

 Books and resources  Comments Off on The Huichol (Wixárika) People’s fight against multinational mining companies
Nov 162014
 

A new feature-length documentary about the Huichol (Wixárika) People, an indigenous group who live in the mountains of western Mexico, has been released. Huicholes: the last peyote guardians is a must-see movie and is already winning praise and awards. Equally importantly, it is helping to raise funds and support for the Huichol as they fight to retain full control over their ancestral territory in the face of threats from federal authorities and multinational mining companies.

The IMDb movie database describes the movie as, “The urgent story of the mystical Wixarika People, the Huicholes: one of the last pre-Hispanic alive cultures in Latin America. Their struggle against the Mexican government and multinational mining corporations to preserve Wirikuta, their most sacred territory and home of the famous peyote cactus. The mining activities of the Canadian companies that got the concessions in 2010 to prospect this protected area, rich in silver, gold and other minerals, are seen by the Wixarika and their supporters as a great menace for the delicate biodiversity of this unique ecosystem, listed by the UNESCO as World Cultural and Natural Heritage. An unequal and controversial fight from today that triggers the global debate between ancient cultural values, the exploitation of nature and the inevitable development of the peoples.”

I have to agree with my long-time editor and colleague David McLaughlin that this documentary about the Huichol portrays “Canadian commercial imperialism at its worst.”

Mexico’s varied geography has made it a premier destination for all kinds of adventure tourism, from caving and canyoneering to jungle treks, white-water rafting and rock climbing.

This 6-minute video shows mountaineer Alex Honnold climbing the 460-meter (1500-feet) high rock face known as El Sendero Luminoso near Monterrey in northern Mexico. What makes this climb special (and slightly scary to watch) is that Honnold climbs solo and without any safety measures such as ropes.

Interviewed for National Geographic Adventure before he had seen the video, Honnold said, “I’m not sure what the video shows, but my true solo was all alone with no photogs [photographers] or helis [helicopters]. We then went back and filmed on big portions of it. In my mind there’s a clear difference between personal climbing—the actual solo—and work days—the filming afterward.”

“The Spires” in El Potrero Chico climbing area (Wikipedia photo)

The El Sendero Luminoso rockface is in an area known as El Potrero Chico, a short distance from Monterrey, near the town of Hidalgo.

The Wikipedia entry for El Potrero Chico describes it as having “a large range of different climbs, most of them in the 5.8 to 5.13 grade. The type of climbing can range from steep overhanging face to easy slab. The rock is usually quite sharp. The climbs are mostly situated in a canyon at the entrance of the park, while the interior offers undeveloped mountain terrain with many mountain biking routes, ranging from very easy to expert options.”

According to Wikipedia, El Potrero is “considered one of the top 10 locations to sport climb in the world. In addition to well over 500 routes, the area boasts the second longest sport route in North America, Timewave Zero, with 23 pitches and over 2,000 feet (610 m).”

Mexcaltitán, a magical island town in Nayarit

 Other  Comments Off on Mexcaltitán, a magical island town in Nayarit
Nov 102014
 

A short distance north of San Blas, in Nayarit, is a small island called Mexcaltitán. With barely four thousand inhabitants, it would scarcely be expected to have any real link to Mexico City, the world’s greatest metropolis of some twenty million people. But it does, and the link is to be found in the amazing story of the founding in 1325 of the Aztec capital Tenochtitlan, the city which was later conquered and sacked by the Spanish and rebuilt as Mexico City.

The island and village of Mexcaltián, Nayarit

The island and village of Mexcaltián, Nayarit

Historians have long wondered about the origins of the Mexica people, or Aztecs as they later became known. There is virtually no evidence of them before they founded the highly organized city of Tenochtitlan in 1325. Clearly such a civilization cannot just have sprung up overnight. So, where did they come from? Mexica (Aztec) legend tells of a long pilgrimage, lasting hundreds of years, from Aztlán, the cradle of their civilization, a pilgrimage during which they looked for a sign to tell them where to found their new capital and ceremonial center. The sign they were looking for was an eagle, perched on a cactus. Today, this unlikely combination, with the eagle now devouring a serpent, is a national symbol and appears on the national flag.

Map showing location of Marismas Nacionales

Map showing location of Marismas Nacionales

In recent years more and more evidence suggests that Aztlán may be far from mythical and that Mexcaltitán, the island in Nayarit, could be its original site. Ancient codices (pre-Columbian hand-painted manuscripts) prove that the Aztecs’ search for a new place to live was ordained by Huitzilopochtli, their chief god. It began in about AD1111 when they departed from an island in the middle of a lake. Their two hundred year journey took them through present-day Nayarit, Durango, Zacatecas, Jalisco, Michoacán, Guanajuato and Querétaro, and they may well have rested awhile on encountering familiar-looking islands in the middle of lakes such as Chapala and Pátzcuaro.

One of Huitzilopochtli’s alternative names was Mexitli and the current spelling of Mexcaltitán could be interpreted as “Home of Mexitli”, or thus, “Home of Huitzilopochtli”. In fairness, it should be pointed out that if the original spelling was Metzcaltitán (and “tz” often became transliterated to “x” down the centuries), then the meaning would become “Place next to the home of the Moon”.

Whatever the etymology of the name, early codices such as the Boturini Codex show the early Aztecs setting out from an Aztlán surrounded by water, in small canoes. The Mendoza Codex, depicting life in Tenochtitlan, has illustrations of similar canoes and, in both codices, the canoes and method of propulsion by punting show remarkable similarity to the present-day canoes of Mexcaltitán. Visitors to the island still have to undertake a canoe or panga ride to reach the village and it is an intriguing thought that the Mexica/Aztecs were doing exactly the same over eight hundred and fifty years ago.

Further evidence comes from an old map of New Spain. Drawn by Ortelius in 1579, it shows Aztlán to be exactly where Mexcaltitán is to be found today, though perhaps at the time this was largely conjecture.

The street plan of Mexcaltitán, best appreciated from the air, is equally fascinating. Two parallel streets cross the oval-shaped island from north to south, and two from east to west, with the modern plaza in the middle, where they intersect. The only other street runs around the island in a circle, parallel to and not far from the water’s edge. This street may have been the coastline of the island years ago and may even have been fortified against the invading waters of the rising lake each rainy season. Today, as then, for several months in summer the streets become canals, bounded by the high sidewalks each side and Mexcaltitán becomes Mexico’s mini-Venice as all travel has to be by canoe.

This street pattern has cosmic significance. It divides the village into four quarters or sectors each representing a cardinal point, reflecting the Mexica conception of the world. The center can be identified with the Sun, the giver of all life. The Spanish, as was their custom, built their church there, and today the central plaza with its bandstand is the obvious focal point of the community. Small shops, a billiards hall, a modern, well-laid out museum, and an administrative office complete the central area of the village.

Low houses, of adobe, brick and cement, line the dirt streets and extend right down to the water’s edge, in some cases even over the water’s edge into the surrounding lake, on stilts. Land on the island is at a premium and, with an ever-growing population, saturation point is very near.

A century ago, the locals turned on some foreigners who came to hunt female egrets, valued for their plumes back in the days when feathers adorned fashionable ladies’ hats. Today, provided only photos are taken, all visitors are welcomed! The villagers celebrate one of the most unusual and distinctive fiestas in all of Latin America. On 29 June each year they organize a regatta which consists of a single race between just two canoes, though naturally hundreds of other pangas are filled with spectators. One of the competing canoes carries the statue of Saint Peter from the local church, the other carries Saint Paul.

Elaborate preparations precede the race. The village streets are festooned with paper streamers and the two canoes are lavishly decorated by rival families carrying on an age-old tradition. The Ortíz family is responsible for St. Peter’s canoe, the Galindo family for St. Paul’s. The statues of the two saints are taken from the church and carried in procession to the boats. A pair of punters has previously been chosen from among the young men of the village for each boat. The punters have been suitably fortified for the contest with local delicacies such as steamed fish, shrimp empanadas, and the local specialty, tlaxtihuile, a kind of shrimp broth. Each boat, in addition to the punters and the statue of the saint, carries a priest to ensure fair play. The race starts from the middle of the eight kilometer long lake after a short religious service in which the priests bless the lake and pray for abundant shrimp and fish during the coming year. Then surrounding spectator canoes, some with musical bands, and others shooting off fireworks, move aside and the race begins.

Nowadays, St. Peter and St. Paul take it in turns to win, most considerate in view of the violence which years ago marred the post-race celebrations when the race was fought competitively. The ceremonial regatta safely over, land based festivities continue well into the night.

A canoe ride around the island takes about 30 minutes and provides numerous photo opportunities as well as many surprises including a close-up view of the island’s only soccer pitch—in the middle of the lake, under half a meter of water. The local children are, perhaps not surprisingly, expert “water soccer” players, a fun sport to watch.

Even if you’re not interested in the island’s past and are unable to see it on fiesta day, your trip to Mexcaltitán will be memorable. This extraordinary island and its village have to be seen to be believed.

The island is reached from the Tepic-Mazatlán highway, Highway 15. There are two alternatives. The northern route is signposted 73 kilometers north of Tepic; it starts with 26 kilometers of paved road crossing swampy paddy fields, followed by 16 kilometers of well-graded dirt road to Ticha, the landing-stage for boats to the island. The drive is through a naturalist’s paradise, teeming with wildlife. The equally scenic southern route begins 57 kilometers from Tepic and is via Santiago Ixcuintla (basic hotels only; don’t miss visiting the center for Huichol Indian culture and crafts) and Sentispac. It leads to the La Batanga landing-stage, and is fully paved.

The 2014 Tecate SCORE Baja 1000 off-road race

 Other  Comments Off on The 2014 Tecate SCORE Baja 1000 off-road race
Nov 082014
 

Entrants in the 2014 Tecate SCORE Baja 1000 off-road race have to complete a grueling off-road route that runs almost the entire length of the Baja California Peninsula. The race starts in Ensenada, Baja California, and ends in La Paz, Baja California Sur (see map). The approximate point-to-point distance is 1820 kilometers (1,130 miles). The 47th Tecate SCORE Baja 1000 race is being held this year from 12-16 November.

Route of Score 1000 Baja off-road race

Route of Score 1000 Baja off-road race

The race gives us a good excuse to offer this brief introduction to the geography of the very long, narrow Baja California Peninsula, which stretches for about 1150 km (700 mi).

In the north, it is composed of mostly granite, while the south is mostly marine sediments and lava.

To the east of the peninsula, the Sea of Cortés (Gulf of California) occupies a trough resulting from a series of faults which are linked to the famous San Andreas Fault system in California. Prior to the opening up of the Gulf of California, the peninsula was attached to the mainland. There are several volcanic islands in the Gulf.

The backbone of the peninsula is a crystalline mountain system with many peaks exceeding 1500 m (5000 ft) and some reaching as high as 3000 m (10,000 ft). The mountains have longer, gentler western slopes and steeper more rugged eastern slopes. Thus, as viewed from the Gulf of California, the Baja Mountains and the Western Sierra Madre look steep, foreboding and very rugged, while from the other side they look more subdued.

Climatically, almost the entire peninsula is extremely arid and forms the western part of the Sonoran Desert. It receives only limited and infrequent rainfall. However, the southern part of the peninsula does experience the occasional hurricane (such as Hurricane Odile earlier this year) which brings powerful winds and torrential downpours.

Population is distributed very unevenly on the Baja California Peninsula. The heaviest concentration of people is found in the extreme north, close to the U.S. border, a region which includes the cities of Tijuana, Mexicali and Ensenada. There are very low densities of population in most of the middle section of the peninsula, where the most important settlements include Guerrero Negro, Santa Rosalía,Ciudad Insurgentes and Ciudad Constitución.

The southern portion of the peninsula has attracted more settlement and this area, which includes San José del Cabo, Cabo San Lucas, La Paz and Todos Santos, is one of Mexico’s premier tourism regions.

The regional geography of music in Mexico

 Other  Comments Off on The regional geography of music in Mexico
Nov 062014
 

Here are brief descriptions of some of the most commonly heard forms of regional music within Mexico. What you hear depends on where you travel!

Mariachi

For many decades, mariachi has been widely considered to be the quintessential Mexican folk-music genre, and has become an important symbol of Mexican music and culture.

A mariachi band is a term used to describe an ensemble band of five or more musicians that wear the traditional costume of a charro or Mexican cowboy. The costume consists of a waist-length jacket, tightly fitted pants and boots and a large sombrero. The jacket, pants and sombrero are elaborately decorated with colorful metal ornaments and intricate embroidered designs.

The unique sound of mariachi music is created by combining trumpets, violins, and guitars with two traditional Mexican instruments, the vihuela and the guitarrón. The music is characterized by loud, hard driving rhythms, spirited melodies and humorous lyrics. Shouts and cries (gritos) are periodically given while a song is being sung, giving the music an additional lively character.

Ranchera

Another very popular Mexican music form is the ranchera (ranch song), which originated during the time of the Mexican Revolution. It is basically cowboy music, and the singers dress in the traditional style of the Mexican horseman with tight breeches, jacket, boots, gun holsters and a large sombrero.

The lyrics of ranchera songs typically deal with rural life, unrequited love, or about the struggles of ordinary people living in the country. The songs are sometimes joyous and sometimes nostalgic or tragic, and are often sung in a very dramatic and passionate manner, with the singer crying out “Ay, ay, ay, ay, ay!” at various points.

Norteña

Another popular music genre, particularly in northern Mexico, is the norteña. This form of music has its origins in the ballads that were traditionally sung by people living along the USA-Mexico border. This music style is typically a hybrid of many other musical forms, including the waltz, polka, and country music.

Norteña is high energy music, driven by the accordion and the booming bass sound of the bajo sexto, a large 12-string guitar. The lyrics of norteña songs typically deal with stories of life along the border, illegal immigrants, outlaws and desperados, drug dealers (narcotraficantes), corrupt public officials, rejected lovers, etc.

Many norteña bands are quite large, with a full horn section and strings. The genre’s most famous group, Los Tigres del Norte has cultivated a large number of fans both in Mexico and in the USA.

Banda

Banda (Band) refers to the form of music played by large brass ensembles that first appeared in the northern Mexican state of Sinaloa several decades ago. A typical banda ensemble features trumpets, trombones, tubas and percussion instruments, and may include keyboards. String instruments are used sparingly, if at all. Banda sounds somewhat similar to American Big Band music, but with a distinctive Hispanic twist.

The table shows the destinations of Mexico’s major export flows, excluding petroleum-related exports, for the first five months of 2014. (All data from Pro-Mexico.) It is no surprise that Mexico’s two main export partners are the USA and Canada, its partners in the North American Free Trade Agreement (NAFTA), but the other countries in the list are far harder to guess, and even most economists would struggle to get them in the right order!

Mexico's leading exports by country, Jan-May 2014 (Pro-Mexico, 2014)

Mexico’s leading exports by country, Jan-May 2014 (Pro-Mexico, 2014)

Spain, on account of its colonial dominance and shared language, has long been a major destination for Mexican exports, whereas China (#4 on the list) is a recent entry, and one that has risen rapidly in importance for a wide variety of products. The other Asian countries on the list of the top 15 export destinations are Japan, India and South Korea.

All the remaining top 15 destinations for Mexican exports are in either Europe or Latin America.

In terms of the items exported, vehicles of various categories clearly lead the way by a wide margin, while various electrical or electronic items (telephones, televisions, computers) are also important. It appears that Japanese consumers must like Mexican pork, since that is Mexico’s leading export to Japan.

And who would have guessed that Mexico also exports significant quantities of iron and steel waste to India, or lead minerals to Italy?

How does Mexico’s water footprint compare to that of other countries?

 Books and resources  Comments Off on How does Mexico’s water footprint compare to that of other countries?
Oct 292014
 

In a previous post, we saw how Mexico is a major net importer of “virtual” water. In this post we take a closer look at Mexico’s water footprint. The data throughout this post come from The Water footprint of Mexico in the context of North America (pdf file).

Individual products each have their own water footprint in terms of the total amount of water involved in their production, processing and marketing. For example a single cup of coffee represents (on average) a water footprint of 140 liters. Other water footprints include:

  • A single letter-sized sheet of paper – 10 liters
  • Microchip – 32 liters
  • Pair of leather shoes – 8000 liters
  • Glass of milk 200 liters
  • Glass of wine 120 liters
  • Tomato 13 liters
  • Hamburger (150 gram) 2400 liters

From numbers like these, it is possible to calculate the water footprint for an individual consumer in a particular country, and also for an average consumer in each country.

How does the water footprint in Mexico compare to other countries?

The water footprint of Mexico (WWF 2012)

The water footprint of Mexico (WWF 2012)

The graphic shows that Mexico’s total water footprint (all consumers) is 197,425 Hm³, of which 92% is agricultural, 3% industrial and 5% domestic. Only 57% of Mexico’s water footprint is internal, the remaining 43% is external (ie water used in other countries to make or produce items imported into Mexico). The average water footprint per person in Mexico comes to 5419 liters/day (or 1978 m³/year).

The global average water footprint (all countries, all consumers) in 2010 was 1,385 m³/y. However, some countries have much higher average water footprint/persons than others. For example, the average consumer in the USA has a water footprint of 2,842 m³/y, whereas in China and India the average water footprints are 1,071 and 1,089 m³/y respectively.

The water footprint of an average consumer worldwide  is primarily determined by their consumption of cereal products (contributes 27% to the average water footprint), followed by meat (22%) and milk products (7%).

It should be remembered that countries which heavily rely on foreign water resources may have significant impacts on water consumption and pollution elsewhere.

The following account of Mexico’s traditional (folkloric) and introduced musical instruments consists of extracts from an article by Andrea Teter. [1]

Pre-Columbian instruments

Archaeologists have noted the existence of more than 1,400 musical instruments used in pre-Columbian Mexico and Central America. These were used primarily for religious, and healing rituals and for ceremonies, but also for war, dances, fiestas and entertainment. Some of these instruments, primarily the huehuetl, and teponaztli, both percussion, and the tlapitzalli, a four-hole flute, were considered divine or endowed with supernatural powers, say Mexican archeologists, and were worshiped as idols.

Teponaztli

Teponaztli

The Mexica (Aztecs) used flutes and trumpets made of clay, bamboo and metal. Drums, including the ayotl, made of tortoise shells, and other percussion instruments were used extensively. The huehuetl was the principal drum used by the Mexica and was made from animal skin stretched over a hollowed-out tree trunk. The teponaztli was made from hollowed-out trees or dried gourds, and sometimes gold and silver, with grooves or tongues cut into the top. Rich and varied tones are produced when played with small mallets. Pre-Columbian musicians also used cymbals, maracas, bells and even stones to produce their music.

The Youtube clip below is one interpretation of what some of Mexico’s indigenous musical instruments may have sounded like when played:

Europeans arrive

With the invasion of the Spanish, these musical instruments were immediately used to help convert the indigenous population to Christianity, while the Conquistadors began introducing European musical methods and instruments. A Franciscan missionary, Pedro de Gante, established the first music school in Mexico in 1523 and trained students in the construction and playing of European instruments.

Little by little, all of the European instruments were introduced to Latin America, starting in the 16th century with organs, guitars, harps and flutes, and later followed by the violins, trumpets, mandolins and accordions. Especially important and influential were guitars, which rose to prominence in the seventeenth century, as an easier-to-play alternative to the lute.

Six-string guitars, viheulas, became extremely popular in Mexico with other instruments of the same family also put into general use: five-string charangos, tiples, or treble guitars, and a large 12-string guitar similar to a bass, the bajo sexto.

Another string instrument that became popular in Mexico was the mandolin. The mandolin, which comes from Southern Italy, is the most recent development of the lute family. It was popularized in Mozart’s “Don Giovanni” and Verdi’s “Othello”.

The salterio, originally from Egypt, is a stringed instrument a little larger than a briefcase with a sound resembling a harpsichord and a playing method resembling a steel guitar or autoharp. The musician plucks the 97 strings while it rests on his knees; the sound is unique and quite beautiful.

Once the Spanish began importing slaves from Africa, these blacks began constructing marimbas, which imitated the African xylophone. As early as 1545, a Spanish scribe in the state of Chiapas wrote of an instrument of eight wood bars played with heavy sticks by the local natives at tribal ceremonies. The modern sophisticated Mexican marimbas was developed by Chiapas musician Corazon Borraz, who in 1896 brilliantly added a second row of half-tone bars to the common single row (like a piano’s black keys) adding to the musical scope of the original instrument, allowing it to play more complex music.

marimba

A marimba band: two marimbas plus guitar and drums

Today, a concert marimba can be three meters long, have 70 keys and weigh more than 55 kilos. This grand instrument demands four musicians; the bass man at the wide end with two sticks or baguetas having small rubber balls on the striking tips. This end has long resonance boxes hanging below the sound keys. Then the harmonics man with one or two sticks in each hand above shorter resonance boxes. Then comes the melody maker and leader, wielding two sticks per hand; then the narrow end controlled by the treble master, a stick in each hand producing counterpoint to the melody. Talk about a compact orchestra!

The variety of instruments Mexican musicians and composers have access to has resulted in a distinctive music for this country. At least one Mexican composer, Carlos Chavez, has gained international fame with his integration of Mexican pre-Hispanic instruments in his works such as “Sinfonia India,” “Xochipilli” and “Macuilxochitl.”

Some Mexican composers have been even more innovative. For example, Julián Carrillo (nominated for the Nobel Prize in Physics in 1950), one of Mexico’s top violinists, invented a microtonal music system known as Sonido 13. The system became sufficiently famous that Carrillo’s birthplace in the state of San Luis Potosí felt obliged to rename itself Ahualulco del Sonido 13: an interesting place to visit for any geographers interested in microtonal music! Ahualulco del Sonido 13 is located 39 kilometers northwest of the city of San Luis Potosí. Leaving that city, first follow federal highway 49 towards Zacatecas and then turn north on the road signed Charcas.

In the webpage’s own words, it is “a powerful interactive tool that enables users to visualize a country’s total trade, track how these dynamics change over time and explore growth opportunities for more than a hundred countries worldwide.”

What is economic complexity?

A country with a high Economic Complexity has a wide range of complex knowledge capabilities related to productive enterprises. Its economy is likely to produce sophisticated products that require a very wide and diverse set of knowledge capabilities. For example, relatively few countries have the capabilities to produce highly complex chemicals or pharmaceuticals, since their production requires very specialized equipment and very precise measuring instruments. Equally, very few countries have nuclear power stations or space stations, since they lack the range of knowledge capabilities needed to build them. At the other end, a very large number of countries have far less complex economies that are capable of producing simple products (basic foods, mineral ores, lumber, garments, shoes, glass, kitchen utensils, furniture) but not products involving more complicated processes or technology

We first discussed the Atlas in 2012 in How “complex” is the Mexican economy?, when we noted that the Atlas ranked Mexico’s Economic Complexity Index (ECI) as #20 of the 128 countries studied. The interactive nature of the online Atlas has added the opportunity to explore many more trends in trade, generating a range of related, visually-appealing infographics.

In particular, choosing Mexico as the country, the Atlas can answer questions such as:

  • What does Mexico import and export?
  • How has Mexico’s trade evolved over time?
  • What are the drivers of Mexico’s export growth?
  • Which new industries are likely to emerge in Mexico? Which are likely to disappear?
  • What are the GDP growth prospects of Mexico over the next 5-10 years, based on its productive capabilities?

Playing with the variables and dates in the Atlas is a really interesting way to explore just how Mexico’s exports and imports have changed over the years. For example, compare these infographics for Mexico’s exports in 1964 and 2010 respectively:

What_did_Mexico_export_in_1964_

Mexico’s exports in 1964

Mexico's exports in 2010

Mexico’s exports in 2010

It is sometimes hard to imagine just how much Mexico has changed in the past fifty years! Overall, at rank #20, Mexico turns out to have an unusually high Economic Complexity Index given its income level. (All the other countries in the top 20 have significantly higher incomes than Mexico).

According to the Atlas, during the rest of this decade Mexico’s GDP should grow relatively rapidly, bringing its GDP rank more in line with its Economic Complexity Index. In general, analyses in the Atlas indicate that during the last few decades countries with higher than expected ECIs compared to their income levels experience more rapid economic growth.

Note, though, that while this relationship is empirically true, it does not explicitly include other factors thought to be important to economic growth such as governance and institutional quality, corruption, political stability, measures of human capital and competitiveness indicators.

Which of Mexico’s states have the fastest growing economies? The map below, based on INEGI data, shows each state’s percentage change in GDP for the three year period from 31 March 2011 to 31 March 2014.

Only one state – Campeche – registered “negative growth” over the period. In Campeche, production from the oil fields that have long been a mainstay of the local economy has been gradually declining.

Besides Campeche, six states grew far slower than the average for Mexico: Durango, Veracruz, Tabasco, Chiapas and Guerrero. Not entirely coincidentally, several of these states are among the poorest in the nation, so their failure to grow as quickly as the average leaves them further behind, increasing the economic inequalities that plague Mexico’s development.

At the other end of the spectrum, the economic growth of six states – Sonora, Chihuahua, Aguascalientes, Guanajuato, Michoacán and Querétaro – easily outpaced the average for the country. Sonora, Chihuahua, Guanjuato, Querétaro, and to a lesser extent Aguascalientes, all benefited from foreign direct investments and new industries, such as those involved in  the vehicle manufacturing and aeronautical sectors.

The case of Michoacán is something of an anomaly, since that state’s economy is still heavily dependent on primary products such as avocados and iron ore. The positive growth in that state may prove to be mainly due to its negative growth in the preceding three years (2008-2011), which meant that it started the three year period shown on the map at an unusually low level. Perhaps more importantly, given the state’s recent political upheavals and gang-related violence, it is highly unlikely that Michoacán will continue to grow anywhere as quickly over the next three years.

Are Monarch Butterflies in danger of extinction?

 Other  Comments Off on Are Monarch Butterflies in danger of extinction?
Oct 182014
 

As a species, monarchs are native to North America, but subsequently island-hopped their way around the world—across the Pacific to Hawaii, Tonga, Samoa, Australia and New Zealand, and across the Atlantic to Europe. In parts of Mexico, particularly in the area around Lake Chapala, there is a healthy population of non-migrating monarch butterflies; these butterflies can count on year-round access to milkweed plants on which to lay their eggs. As a result, it is reasonable to conclude that the species itself is in no danger of extinction.

However, what may be “endangered” is the annual migration of Monarch Butterflies to and from Mexico. This annual migration is categorized as an “endangered phenomenon” by the International Union for Conservation of Nature. Threats to the migration come from climatic change and extremes, as well as from the impacts of human activity. In some years, unusually cold snaps and hailstorms have caused the premature death of millions of butterflies, though, as yet, this has had little if any discernible effect on total monarch numbers. Human activity has greatly reduced the area of the monarchs’ natural overwintering habitats, in both California, for real estate developments, and in Michoacán, due to forest clearance for timber and agriculture. Farming activities in the US have also resulted in the loss of milkweed along the Monarchs’ migratory pathways. This loss may have far more serious consequences on the long-term viability of the annual migration. Without milkweed, the female Monarchs are unable to lay their eggs on a suitable host plant, and the Monarch caterpillars will never acquire their chemical defenses against predation.

The numbers of Monarchs overwintering in Mexico have varied greatly from one year to the next. The graph below, reproduced widely in the press, has been used as evidence that the numbers of migrating Monarchs are in sharp decline. A note of caution is needed, though, since the estimates of numbers used for the graph are based on the area of trees occupied by the butterflies, and not on a direct count (which is clearly impractical!)

Monarch-Trends-1994-2013

The challenge for researchers is to be certain that the density and architecture of trees is similar from one year to the next. If the trees are less densely grouped, for example, one year than the next, in the particular areas occupied by the butterflies, then the area the butterflies need will be correspondingly larger. The lower area in recent years could be at least partially explained by a higher tree density in the overwintering areas, allowing the same number of butterflies to co-exist in closer proximity to each other.

This is not to say that there is not cause for concern. According to the National University (UNAM)’s Environmental Geography Research Center, at current rates of deforestation, the area of overwintering sites for the Monarch butterflies could be reduced by 75% in the next 18 years, leaving just 12,000 ha of suitable habitat. The protected area, established in 2000, covers 560 square kilometers (56,000 ha. or 216 sq. mi) but includes land cleared for pasture, settlement and cultivation. Researcher José López García claims the reserve is losing 3% of its forest each year. He blames clearance and changes of land use more than illegal logging. The rate of forest clearance has been exacerbated by a rapid rise in the population of the El Rosario ejido. El Rosario is the gateway to the most-visited part of the reserve, attracting thousands of tourists annually. The ejido’s population rose by an average of 5.65%/year between 2005 and 2010.

What is Mexico doing about this?

The Mexican conservation strategies for the butterflies are designed to protect their overwintering habitat and provide alternative sources of revenue and employment for local campesinos who depend on the land and forest for their livelihood. After some doubtful years in the early 1980s, there is now a system of formally protected monarch butterfly reserves, and concerted conservation efforts to prevent further destruction of the monarchs’ unique overwintering habitat.

The modest entrance fees to Monarch Butterfly reserves help fund development projects in the local communities. There is a strict code of conduct for tourists to prevent noise, littering and straying from the well-marked paths.

While the new rules have undoubtedly had some success, it is still preferable to visit, if at all possible, during the week and not at the weekend when the reserves are at their crazily busiest.

On a quiet day,pausing to catch your breath in the peace of the forest as you climb the trail, you will then be just as surprised as I first was when you realize that the gentle swishing sound you can hear around you is not the sound of the wind blowing through the tree limbs but the sound caused by millions of tiny wings beating as the butterflies flutter about in the sky.

The Ghost Train (El Tren Fantasma): a case study of the geography of sound in Mexico

 Books and resources, Other  Comments Off on The Ghost Train (El Tren Fantasma): a case study of the geography of sound in Mexico
Oct 162014
 

Geography is not only about things that can be seen, touched and measured. Many branches of geography consider how people think, how communities make decisions and how nations interact.

At a local scale, one of the characteristics that is often overlooked is sound. We often ignore the soundscapes of places, either because we are “too busy” to listen and take in the local sounds, or because we are “too busy” tuning any distinctive local sounds out while using our cell phones or listening to favorite music.

Soundscapes vary greatly from rural areas to urban areas, and from one region to another; Mexico’s urban soundscapes are among the most distinctive on the planet.

In previous posts, we listened to The distinctive sounds of Mexico’s towns and cities; covered our ears as we analysed Noise pollution in Mexico; and also described the amazing Whistled language of the Chinantec people in Oaxaca.

In this post, we take a look at Chris Watson’s intriguing 2011 album “El Tren Fantasma”:

U.K.-based Chris Watson is a preeminent freelance recordist of wildlife and natural phenomena, whose work has been featured in many BBC programs including David Attenborough’s series, The Life Of Birds. As Watson has remarked, sound recording allows you to put a microphone where you can’t put your ears, to enable you to listen to sounds such as the groaning ice of a moving glacier. His work for the BBC was audio vérité but more recently, including in El Tren Fantasma, Watson has experimented with post production techniques to meld field recordings into a narrative.

The result is strangely compelling, dramatic and in some respects, awesome!

The soundscapes of El Tren Fantasma (the title is identical to that of a 1927 Mexican movie) offer a trip from the Pacific Coast to the Gulf Coast of Mexico condensed into little more than an hour.

The first six tracks cover the section of railway best known as the Copper Canyon line, one of the few remaining routes in Mexico with regular passenger service.

El Tren Fantasma has 10 tracks (pun intended):

  1. La Anunciante
  2. Los Mochis
  3. Sierra Tarahumara
  4. El Divisadero
  5. Crucero La Joya
  6. Chihuahua
  7. Aguascalientes
  8. Mexico D.F.
  9. El Tajin; El dia y La noche
  10. Veracruz

If you don’t have time to listen to all 10 tracks, the most interesting, from a geographical point of view, are probably the following:

The trip was nicknamed the ghost train by Watson because there are no longer any passenger trains connecting the two coasts. Several years ago, Watson was the sound recordist for a film crew making a program in the BBC TV series Great Railway Journeys. Even then, part of the line was freight only, but in earlier times, there had been regular scheduled passenger trains across the country.

The promotional material asks potential listeners to, “Take the ghost train from Los Mochis to Veracruz and travel cross country, coast to coast, Pacific to Atlantic. Ride the rhythm of the rails on board the Ferrocarriles Nacionales de México (FNM) and the music of a journey that has now passed into history.”

“In this album, the journey of the ‘ghost train’ is recreated, evoking memories of a recent past, capturing the atmosphere, rhythms and sounds of human life, wildlife and the journey itself along the tracks of one of Mexico’s greatest engineering projects.”

Reviews were almost universally positive.

Several reviewers recognized the connection between the soundscapes of El Tren Fantasma and geography, in some cases also attributing reasons for the decline of passenger train services in Mexico. For example Martin Hoyle, writing in The Financial Times, described how “From desert to rainforest, hummingbirds’ wings to the boom of heat rising from the Copper Canyon, it recalls a beloved passenger train system abandoned by privatisation.”

Pete Naughton in The Daily Telegraph wrote that the sound portrait painted by Watson “jostles with human, animal and mechanical life, filling the room with an atmosphere that is more richly evocative of Central America than any TV travel show I’ve seen. Diesel engines thrum, cicadas chirrup and passengers chatter, sing and argue.”

A reviewer in The Milk Factory (UK) drew attention to the “tremor of excitement as the sound of a diesel engine temporarily swallows the clunking noise of metal on metal and the strident hisses as wheels grind again rails and breaks against wheels”, before adding that, “Watson doesn’t aim to recreate the journey in any consistent chronology. Instead, he gives a taste of what this journey actually was by using nature and wildlife sounds to hint at the landscapes passed on the way.”

Spencer Grady, reviewing El Tren Fantasma for BBCi (UK), wrote that: “While Chris Watson’s previous sets – such as 2003’s critically acclaimed Weather Report – have generally concerned themselves with this planet’s myriad beasts and habitats, this narrative inevitably bears an anthropological mark. Indeed, the first voice we hear doesn’t belong to a cuckoo or coyote, but station announcer Ana Gonzalez Bello putting out one “last call for the ghost train”. It’s an unusually contrived opening gambit, from which point the listener is jettisoned into a collision of screeching breaks, rolling stock rattle and hot hydraulic huff. Over half of El Tren Fantasma’s tracks (pun definitely intended) are given over to locomotive sound – gears shifting, hoots, bells and whistles – climaxing with El Divisadero, where Watson manipulates the monolithic machinations into a surging, phantasmal bellow, like a choir of angels struggling to be heard over the rumbling thrum of running gear.”

For an academic geographer’s perspective on El Tren Fantasma, a good place to start (for those with academic library access) is a recent issue of Transactions of the Institute of British Geographers (Vol 39, No 3, 2014). In “El tren fantasma : arcs of sound and the acoustic spaces of landscapes”, George Revill, of the Open University, draws on Chris Watson’s soundwork “El tren fantasma” to consider “how sound participates in the production of the railway corridor as a complex, animate and deeply contoured historically and geographically specific experience of landscape.”

El Tren Fantasma offers an extraordinarily evocative sound summary of a trip across Mexico; what a shame that there are now so few passenger services left on Mexican railways!

Mexico is a major net importer of “virtual” water

 Books and resources, Teaching ideas  Comments Off on Mexico is a major net importer of “virtual” water
Oct 132014
 

The concept of “virtual water” was developed by Professor J.A. Allan of King’s College (London University) and the School of Oriental and African Studies. Allan used it to support his argument that Middle Eastern countries could save their scarce water resources by relying more on food imports. The idea was sufficiently novel for Allan to be awarded the 2008 Stockholm Water Prize.

In Allan’s words, “The water is said to be virtual because once the wheat is grown, the real water used to grow it is no longer actually contained in the wheat. The concept of virtual water helps us realize how much water is needed to produce different goods and services. In semi-arid and arid areas, knowing the virtual water value of a good or service can be useful towards determining how best to use the scarce water available.”

As one example, producing a single kilogram of wheat requires (on average) around 1.5 cubic meters of water, with the precise volume depending on climatic conditions and farming techniques. The amount of water required to grow or make a product is known as the “water footprint” of the product.

Hoekstra and Chapagain have defined the virtual-water content of a product, commodity, good or service, as “the volume of freshwater used to produce the product, measured at the place where the product was actually produced”. The virtual water content is the sum of the water used in the various steps of the production chain.

Additional examples, showing the water footprint of producing one kilogram of:

  • biodiesel from soya –  11.4 cubic meters
  • beef –  15.4 cubic meters
  • butter –  5.5 cubic meters
  • chocolate – 17.0 cubic meters
  • pasta –  1.85 cubic meters
  • sugar (from cane) –  0.2 cubic meters

While the idea of virtual water has attracted some attention, its methodology is contested, and its quantification is not yet sufficiently precise to offer much potential for policy decisions.

Imports and exports of virtual water represent the “hidden” flows of water involved when food and other commodities are traded from one place to another. The map below (from Hoekstra and Mekonnen, 2012) shows the net imports (imports minus exports) of virtual water for different countries for the decade 1996-2005. Note that only the major flows are shown.

water-virtual-tradeIn North America, both the USA and Canada have a significant positive virtual water balance (i.e. they are major exporters of virtual water), whereas Mexico has a significant negative water balance, and is clearly one of the world’s largest importers of virtual water.

As Allan’s original work suggests, this is not necessarily bad news since it may imply that Mexico is currently using less of its own (limited) water resources than it might otherwise have to. In other words, Mexico’s virtual water imports may be delaying the inevitable crunch time when water usage becomes a critical limiting factor in the nation’s development.

Most monarch butterflies never migrate, but one generation of the North American monarch population undertakes an annual, long distance migration, a journey without parallel in the insect world. Every winter, some one hundred million monarch butterflies fly south into Mexico from the U.S. and Canada. They congregate and spend the winter in a dozen localities high in the temperate pine and fir forests of the states of México and Michoacán.

Where do the Monarchs overwinter?

The exact sites where the butterflies overwinter were only found in the mid 1970s after a search of nearly forty years. Scientists are still unable to explain all the details of this enigmatic annual migration, but their unexpectedly sophisticated navigational ability seems to rely on an incredible innate accuracy in pinpointing their position by using their eyes and antennas to measure the angles of the sun’s rays, compensating for time of day, and ensuring they continue to fly in a southerly direction towards the state boundary separating Michoacán from the State of México.

How fast can they fly?

The tagging of butterflies has proven that they make the 2500 kilometer trip each way at an impressive average speed of 20 km/h, with maximum speeds of up to 40 km/h (25 mph). Monarchs don’t fly at night, partly because they need daylight to navigate and partly because they fly best when sunlight has warmed their wings, like miniature solar panels, raising their body temperatures some 10 to 15 degrees Celsius above ambient air temperatures.

The butterflies are energy-efficient flyers, making regular nectar stops along the way to refuel. One third of their dry body weight is energy-giving fat but far from losing weight on their exhausting journey south, they actually appear to gain it! There are still many mysteries about the monarchs but they certainly provide one of the most amazing natural spectacles to be seen anywhere on earth. Millions of orange butterflies, with black and white-spotted wings, whether flying overhead or, as on cooler days, clinging apparently lifeless to the grey-green fir trees in such numbers that the trees appear to be in blossom, are an absolutely unforgettable sight.

Based on original map design created by Paul Mirocha (paulmirocha.com) for Monarch Watch.

Based on original map design created by Paul Mirocha (paulmirocha.com) for Monarch Watch.

The journey south

In September and October, as temperatures in the U.S. and Canada fall, and food supplies become scarce, the monarchs fly south in small groups. Some of these groups fly only as far as Florida or western California where they spend their winters in milder conditions. But many of the small groups from east of the Continental Divide eventually coalesce and fly much further south, as far as Mexico, arriving en masse in the state of Michoacán towards the end of November.

This migratory group is comprised of as many as 120 million individuals and spends the winter in semi-dormancy, on the pine and oyamel (sacred fir, Abies religiosa) trees found at elevation of about 3050 meters (10,000 feet) along Mexico’s central Volcanic Axis. Until spring comes, in March or April, these butterflies cling to the branches and trunks of the trees, enjoying temperatures between 10 and 16 degrees Celsius, protected from cold northerly winds. Their metabolism slows down in these low temperature, low oxygen conditions and they exhibit movement only on warm, sunny, days.

The generation that flies into Mexico does not mature sexually until the following spring. In February and March, the best months to see them, early spring sunlight begins to penetrate the groves of fir trees, temperatures begin to rise and the forest floor slowly comes alive with new plant growth. The butterflies, having successfully overwintered the worst weather, unfurl their wings and flutter about in search of food and water. As they regain their strength, so they become sexually mature and the mating process starts.

The journey north

After mating, the butterflies begin to leave the reserves, flying back towards the north. Five days later, in northern Mexico and the southern U.S., each female lays two to three hundred eggs on the underside of milkweed leaves. They first check (by smell and touch) that no eggs have already been laid there, and then space their eggs in such a way so as to ensure that each larva that hatches two to three days later will have an adequate supply of food. The larvae grow quickly, changing their skins five times before becoming pupae. After a further two weeks, butterflies emerge, and fly northwards. Each generation of monarchs probably acquires a different chemical “blueprint”, based on the exact species of milkweed it eats, giving it the information it needs to know where to fly. Eventually, by April, the northernmost butterflies reach Canada.

No individual butterfly completes the entire 5000 kilometer round trip. Most of those that fly south die soon after mating in spring (with males often dying in the reserves and never starting their homeward trip), while those who head north cannot hope to survive long into the summer, when normal reproductive cycles, each lasting from four to six weeks, are reestablished.

The last generation of each summer, perhaps prompted by shorter days, soon departs on the next wave of mass migration to Mexico. Those from furthest north will cross the Great Lakes on their return in a single day’s flight, an impressive feat in its own right. They have been spotted flying south at heights up to 1500 meters and exploit thermals to gain height and save energy.

Where to see Monarch Butterflies

Several monarch reserves are open to the public each year. Each has its own distinctive character. Two of the most important reserves are close to the town of Angangueo. Sierra Chincua, north of the town, is the site where the first Canadian-tagged monarch was found in the mid 1970s. This is also where I first saw the butterflies, in 1980, while looking for a potential site for geography fieldwork. It was a serendipitous discovery, and led to me being mistaken for a BBC reporter, but that’s another story!

The most accessible reserve open to the public is El Rosario, south of Angangueo, where there are dozens of souvenir stalls and rustic snack stands—don’t miss sampling the delicious hand-made blue-corn tortillas. The narrow trails in the sanctuary, with information boards at regular intervals, wind steeply several hundred meters uphill, reaching a maximum altitude of 3050 meters. This altitude can cause some shortage of breath and air temperatures are generally low, so be sure to bring a sweater.

El Rosario can be reached from either Angangueo (steeper but more direct approach) or Ocampo. Anyone driving their own vehicle to El Rosario is advised to use the route via San Felipe (on Highway 15) and then Ocampo. From Ocampo any vehicle with adequate ground clearance, including the local taxis, can negotiate the fourteen kilometers to the monarch sanctuary parking lot.

The San Felipe-Ocampo junction on Highway 15 is marked by a line of fruit and soft-drink stalls, many of which in season sell delicious granadas (pomegranates). Also at this junction is an interesting sixteenth century church which, until as recently as 1995, had tombstones in its atrium, unusual in Mexico. Normally, the Spanish buried their dead as far away from the churchyard as possible, presumably to avoid the risk of disease.

Recycled plastic boats for Xochimilco?

 Mexico's geography in the Press  Comments Off on Recycled plastic boats for Xochimilco?
Oct 092014
 

What will they think of next? Officials in Mexico City have plans to provide the tourist zone of the Xochimilco canals with environmentally friendly boats and barges and to gradually substitute the usual wooden ones, which have very high maintenance costs. The plan was unveiled a few weeks ago by Mauricio León, director of infrastructure, modernization and innovation for the Federal District.

Xochimilco (Wikipedia; creative commons)

Xochimilco (Wikipedia; creative commons)

Apparently, the traditional wooden vessels, known as trajineras, with their colorful arches, formerly used mostly to transport goods but now dedicated almost exclusively to tourism, require “an enormous expense” each year since they need to be renovated annually, in part due to “the deterioration in recent years” of the water quality in the canals. According to León, the water contains high levels of fungi that degrade the wood. (Q. In that case, why not clean the water, and keep the traditional designs made of wood?)

Mexico City officials have already launched a prototype of the new, plastic, ecologically-sound craft, and hope that the owners of the traditional gondola-like non-motorized boats will form a cooperative to gradually replace them. The design of the new “technoecological” vessels was created by scientists at the National University (UNAM) and preserves the typical characteristics that have made it a widely recognized symbol of tourism in Mexico.

The great advantage of the new boats, made of recycled PET plastic (some of it no doubt pulled from the canals), polyethylene and volcanic clay is their greater durability and stability. Proponents claim that since they are made of recycled material, unlike the traditional ones for which 20 trees have to be cut down to make each trajiinera, the new boats are much cheaper, require less maintenance and their durability is much greater, with the potential to last up to 120 years.

There is one slight problem: the cost of the machinery required to make them. Authorities hope to persuade the boatmen to form “a cooperative able to get financing for the machines,” which will require an investment of some 5 million pesos ($380,000).

This is a long-term plan, because even when the machines are installed, they can produce only about three or four boats a week, and there are an estimated 1500 trajineras currently plying the canals in Xochimilco.

According to press reports such as Buscan dar “nueva cara” a Puerto Arista (in El Economista), there are plans afoot to develop nearby mangrove swamps as part of an ecotourism project. Local architects in the coastal town of Puerto Arista in Chiapas are backing the project to build what might best be called Mangrove Riviera.

The state government has released this 4-min video that summarizes the plan, with models and images of the area:

The initial investment required to get Riviera Manglar “Pakal Ahau” under way is around $120 million. The major advantage, from the state’s point of view, is that it would open up a new region of the state for tourism, cashing in on the area’s natural wealth, especially its mangroves. Proponents argue that the town could easily become a major center for ecotourism and that provided that the project incorporates a high degree of sustainability, and prioritizes the cultural identity of each location, it could be a model for similar projects elsewhere.

The six main places involved in Riviera Manglar “Pakal Ahau” are

  • Puerto Chiapas
  • Zacapulco
  • La Encrucijada
  • Costa Azul
  • Chocahuital
  • El Gancho

The project would extend to a subregion including Bahía Paredón, Boca del Cielo, Playa del Sol, Bahía Marías, El Madresal, Mojarras, Laguna La Joya, Cabeza de Toro, Cerro Bernal, Manglares and Villa Tortuguero.

In time, Puerto Arista could become another “tourist gem” in Chiapas and offer an interesting continuation of the long-standing Ruta Maya.

Mexico’s 2013 avocado harvest and exports

 Updates to Geo-Mexico  Comments Off on Mexico’s 2013 avocado harvest and exports
Oct 042014
 

Mexico is the world’s largest producer and exporter of avocados. The avocado harvest for the 2013/14 season was close to 1.5 million metric tons, a new record. More than 90% of Mexico’s avocados are grown in the state of Michoacán, where 12% of all agricultural land is currently under avocado orchards.

Avocado-growing states

Avocado-growing states

Mexico produces about 1.5 million metric tons of avocados a year, on 170,000 hectares in 27 states. The principal producing states are Michoacán 1.2 million tons, Jalisco 87,000; State of México 56,000; Nayarit 34,000; Morelos 27,000; Guerrero 14,000.

Avocado exports have risen sharply and, in the first half of 2014, totaled 353,000 metric tons, worth 800 million dollars, 29% higher than for the same period a year earlier. The most important markets for Mexican avocados are the U.S., Japan, Canada, Central America and Europe, but demand for avocados in Asia, especially China, is rising very quickly.  Exports to China rose 724% for the period to 1,260 metric tons, worth 3 million dollars.

Exports to the USA of avocados were worth 651 million dollars, 31% higher than a year ago; exports to Japan reached 62 million dollars, up 29%; and to Canada 41 million dollars, up 33%.

One of the largest open-pit copper mines in the world, the Buenavista del Cobre mine in Cananea produced over 200,000 metric tons of copper in 2012. The mine, opened in 1899, is located approximately 40 kilometers south of the border between Arizona and Sonora, Mexico. The open-pit mine was estimated to contain 26.874 million metric tons of copper reserve as of December 2012.

This mine was the location of a 2014 toxic spill: Toxic spill in Sonora copper mine causes environmental disaster

The ore is refined at an on-site concentrator, which has a milling capacity of 77,000 metric tons/day. The concentrate output is transported to the smelter at La Caridad by rail. Also present are an on-site leaching facility and two solvent extraction and electro winning (SX/EW) plants, with an annual production capacity of 55,000 metric tons of copper cathode.

The active, 2-kilometer-diameter Colorada Pit (top right of image below) is recognizable in this astronaut photograph by the concentric steps, or benches, cut around its perimeter (see larger image). These benches allow for access into the pit for extraction of ore and waste materials.

A leachate reservoir for removal and evaporation of water pumped from the mine workings is located to the east of the mine (image lower left). The bluish-white color of deposits near the reservoir suggests the high mineral content of the leachate.

Mexico’s annual GDP/person now stands at $16,463

 Updates to Geo-Mexico  Comments Off on Mexico’s annual GDP/person now stands at $16,463
Sep 292014
 

Recent World Bank figures reveal that Mexico’s GDP/person in 2013 reached $16,463 a year, an increase in GDP/person of 1.8% since 2012. (All figures in US dollars). Mexico’s 2013 GDP/capita is well above the Latin America and Caribbean average of $14,978.

The GDP figures are based on purchasing power parity (PPP) which overcomes gross distortions resulting from differences in exchange rates. For example, a haircut of the exact same quality might cost $15 in the USA, $5 in Mexico and $1 in China. Using the PPP approach, this same haircut would count as a $15 contribution to the GDP of each of the three countries.

Mexico’s GDP/person has grown at an average rate of 4.5%/year since 1991, according to the World Bank. Back in 1991, the GDP/person averaged $6,320.

Mexico’s GDP/person has risen quite sharply since 2008, when the comparable figure was $14,810, though its world rank (#80) is essentially unchanged. The figures suggest that economic growth has outstripped population growth over the past five years, making Mexicans better off (on average), and able to afford more goods and services, now than they were then.

Since 1991, Mexico’s GDP/person has declined in only three years:

  • 1994-1995 – decline of 10% due to world economic crisis
  • 2000-2001 – decline of 0.2%
  • 2008-2009 – decline of 2.2% due to world economic crisis

These figures suggest that Mexico’s economy has become more resilient when there is any slump in global markets.

Mexico hosts 2014 World Tourism Day

 Books and resources, Mexico's geography in the Press  Comments Off on Mexico hosts 2014 World Tourism Day
Sep 272014
 

Today Mexico is hosting World Tourism Day, so this seems like a good time to review the state of Mexico’s tourism sector. The official celebrations are being held in the city of Guadalajara.

The decision by The World Tourism Organization that Mexico should host the 2014 World Tourism Day recognizes Mexico’s importance in world tourism. Mexico is the 13th most popular international destination in the world. In 2013, it welcomed 23.7 million international tourists, who spent 13.8 billion dollars in the country. World Tourism Day 2014 highlights tourism’s social, cultural, political and economic benefits, and its importance in community development.

Earlier this year, Mexico’s Tourism Secretariat published a detailed analysis of the Tourism Industry in Mexico in 2013.

The text of the magazine format publication (link above) is in Spanish, but it includes lots of graphs and maps showing tourism’s trends and patterns. The 21 pages of information cover topics from the origin and spending of tourists to cruise ship ports, hotel occupancy, and number of international flights. The publication offers a wide variety of data and an ideal basis for students who want to design and produce infographics about tourism.

And how is tourism doing in 2014?

So far, all the signs are positive. The number of international visitors for the first half of the year was up 19.6% to 14.2 million, compared to the 11.9 million recorded for the first six months of 2013. Spending in the first half of the year was up 17.6% to 8.435 billion dollars.

Illegal pipeline connection causes oil spill in northern Mexico

 Mexico's geography in the Press  Comments Off on Illegal pipeline connection causes oil spill in northern Mexico
Sep 222014
 

The illegal tapping of a Pemex oil pipeline in the northern state of Nuevo León caused an oil spill in August 2014 that contaminated a 6.5-kilometer-long stretch of the San Juan River.

According to Víctor Cabrera, state delegate for the Federal Attorney for Environmental Protection (Profepa), about 23 kilometers of channels (mostly irrigation channels) have been affected in total. Profepa advised residents to avoid using water from the places affected and not to consume local fish.

The illegal connection to the Madero-Cadereyta pipeline was first detected on 16 August 2014, and has been attributed to the criminal activities of organized crime. It allowed some 4000 barrels of crude oil to spill into the San Juan River.

The spill affected the agricultural communities of Mexiquito, La Fragua, Soledad Herrera, Santa Isabel, Hacienda Dolores, La Concepción and San Juan, home to approximately 6000 people.

The Nuevo León state governor Rodrigo Medina told reporters that an analysis carried out by water and drainage authorities and the National Water Commission (Conagua) had shown that the local aquifers had not been contaminated. The oil spill did not reach El Cuchillo Dam, located some 70 kilometers downstream from the spill, which is one of three main reservoirs supplying potable water to the Monterrey metropolitan area.

More than 500 workers from Pemex and other organizations have been employed to clean up the spill. Within two weeks, 90% of the oil spilled had been recovered and removed, according to a Pemex report. Officials expect the clean-up work on the river banks and in the irrigation ditches to take another two months to complete.

Mexico’s shrimp farms tackle disease crisis

 Updates to Geo-Mexico  Comments Off on Mexico’s shrimp farms tackle disease crisis
Sep 202014
 

Mexico’s total shrimp production in 2007 was 178,000 tons. This total masks a significant trend in shrimping. The high-seas catch has declined since 1990 and less than a third of the total catch now comes from the 2100-vessel specialist shrimping fleet based in the port of Mazatlán. On the other hand, production of fish-farmed (“cultivated”) shrimp has risen sharply over the past 20 years and now accounts for almost 70% of total national production. In the past 24 months, fish-farmed shrimp have been hit by a serious disease, which has caused high mortality and a drop in production.

The main shrimp producing states are Sinaloa (520 shrimp farms; 35,000 hectares of shrimp ponds; 40% of cultivated shrimp production), Nayarit and Sonora (see map).

Wild shrimp

Catches of wild shrimp have been in decline. Shrimp fishermen are worried about the overfishing of shrimp stocks in shallow coastal waters, allegedly due to clandestine fishing by non-authorized boats. Pollution of coastal waters from agricultural chemicals is also a major concern.  According to Adolfo Gracia Gasca, a researcher at UNAM’s Instituto de Ciencias del Mar y Limnología (ICMyL), only two species of wild shrimp are NOT overexploited: the brown shrimp in the Gulf of Mexico, and the brown shrimp in the Pacific.

Among the many wild shrimp populations that have collapsed are the white and pink shrimps of the Gulf of Mexico. Catches of pink shrimp in the Gulf of Mexico declined from 10,000-12,000 metric tons a year in the 1980s to around 500 metric tons in recent years. Catches of white shrimp in the same area over the same period fell from 1,600 metric tons/year to less than 200 tons/year. The major problem has been the failure to enforce a closed season for shrimping during their main reproductive periods. On the Pacific coast (including the Sea of Cortés), shrimping resumed on 5 September 2014.

The Shrimp Trade

Shrimp exports are worth $360 million a year. Shrimp imports have risen sharply in the past two years as disease has reduced domestic production. Indeed, Mexico is currently having to import more frozen shrimp than it exports.

Mexico’s shrimp exports in the first half of 2014 were worth US $91.4 million, slightly down from 2013, while imports shot up 935% to $106.6 million. Mexico is importing shrimp from Ecuador, Honduras, Guatemala, Nicaragua and Belize.

Cultivated shrimp

As a consequence of Early Mortality Syndrome (EMS), the production of farmed shrimp dropped sharply between 2012 and 2013, but is expected to recover in 2015. EMS first appeared in 2009 in the southern part of China, and then spread to Vietnam, Malaysia and Thailand. According to SAGARPA, the disease shows up in the first 20 to 30 days of life of the shrimp, and especially affects tiger (Penaeus monodon) and white (Litopenaeus vannamei) shrimp. The disease adversely impacted thousands of producers, with shrimp mortality rates as high as 98%.

The strain of EMS found in Mexico is very similar (but not identical) to the Asian strain. It is unclear how it arrived in Mexico and whether or not it was transferred across the Pacific.

The National Aquaculture and Fishing Commission (Comision Nacional de Acuacultura y Pesca—CONAPESCA) sets the closed season for fishing and shrimping. In general, the closed season is timed to coincide with the shirmp’s summer breeding season.

What is being done about EMS?

Among the strategies being adopted to combat the adverse impact of EMS are research, provision of financing and limits on shrimp imports from infected regions.

In June 2013, a breakthrough in EMS research was reported, when investigators attached to Kinki University and the National Research Institute of Aquaculture in Japan showed that the disease repeatedly manifests itself in ponds where the pH levels are between 8.5 and 8.8.

Shrimp farmers have needed emergency financing to help them restock shrimp ponds. In 2013, fish farmers in Sinaloa received $75 million to help with shrimp production and exports.

In April 2013, Mexico’s Agriculture, Fisheries and Food Secretariat (SAGARPA) ordered the temporary suspension of shrimp imports originating from China, Vietnam, Malaysia and Thailand. The suspension included all tiger and white shrimp, whether live, raw, cooked, dehydrated or “in any presentation”. However, this strategy was criticized by international experts as “counterproductive”, given that there is no evidence for EMS being spread via dead shrimp.

Which countries have the most promising crops of leaders coming up through the ranks today, and where in the world are there more young people likely to develop into business leaders tomorrow? And how can leadership be measured at all? SHL, a U.K.-based talent management consulting firm, released a study in 2012 that aims to provide answers to those questions.

SHL is a giant in the world of employee assessments, with more than 10,000 clients in over 100 countries. It offers services to consultancies like Deloitte and KPMG, multinationals like Unilever and organizations like the United Nations and the European Personnel Selection Office.

This year, executives at SHL decided to mine data from past employee assessments and try to shed some light on the leadership potential in the many countries where it works. The SHL data came from 1.05 million client surveys gathered between 2006 and 2011. It focused on eight different skill areas to measure leadership capability: initiating activity and deciding, supporting and cooperating, interacting with and presenting to others, analyzing and interpreting data, creating and conceptualizing ideas, organizing and executing plans, adapting and coping with others, and finally, performing and achieving.

In September 2012, SHL published a list of the countries it believes have the greatest percentage of effective leaders, and those that it sees as most likely to develop leaders within the next three to five years. The list of current leaders may not be that surprising. The report ranks the country with the most leaders today as Hong Kong (treated as a separate country, though it is a special administrative region of mainland China), followed by Germany, the U.K., Australia, U.S.A., Canada and Switzerland.

The country that emerges as that with the most future leaders is… Mexico. According to SHL, Mexico’s “market is becoming more international and its leaders are strengthening in several different categories.”

This is an interesting analysis, but only time will tell whether or not it holds much validity!

Test wells being drilled to assess Mexico City’s deep water aquifer

 Mexico's geography in the Press, Updates to Geo-Mexico  Comments Off on Test wells being drilled to assess Mexico City’s deep water aquifer
Sep 132014
 

Pemex, Mexico’s state-owned oil giant, will start drilling the first of two deep exploratory wells in Mexico City later this month to investigate an aquifer deep below the city that is believed to hold vast quantities of potable quality water. For further background, please see our previous post on this topic:

The test wells are part of a $30 million multi-agency study now underway that incorporates experts from the Water System of Mexico City (SACM), the National Water Commission (CONAGUA), the engineering and geology departments of the National Autonomous University of Mexico (UNAM), and Pemex, which is providing the technology to drill the wells.

Later this month, Pemex will start drilling the first 2000-meter-deep test well in the Magdalena Mixhuca Sports City area, in the eastern part of Mexico City. Each well will cost an estimated $7.6 million to complete.

Ramón Aguirre, the CEO of SACM, says that the two test wells will target two different zones, increasing the chances of demonstrating the value of the aquifer as a viable source of water for Mexico City. In particular, Aguirre expects the wells to help confirm that there is an impermeable cap of clay separating the deep aquifer from the principal aquifer in the area (from which water is already extracted). An impermeable layer would mean that water could be safely removed from the deep aquifer without leading to downward drainage of water from the aquifer above. It is expected to take about two years for the initial studies to be completed.

In its National Water Plan, CONAGUA has warned that population growth in the Valley of Mexico could result in serious water shortages by 2030, reducing annual availability from about 4,230 cubic meters/person to less than 1,000 cubic meters/person.

The major aquifer currently used lies at a depth of between 60 and 400 meters and is heavily over-utilized. There are about 630 wells in the Federal District alone; all are overexploited and have an average life expectancy of 30 years. Current extraction from the aquifer is around 17,000 liters/second, while its natural recharge capacity is only 8000-9000 liters/second. It is believed that the deep aquifer could be capable of supplying approximately 5000 liters/second.

Toxic spill in Sonora copper mine causes environmental disaster

 Other  Comments Off on Toxic spill in Sonora copper mine causes environmental disaster
Sep 112014
 

A toxic spill at a copper mine in the northwestern state of Sonora is the Mexican mining sector’s worst environmental disaster in recent history.

The mine is owned by mining giant Grupo México, Mexico’s largest mining corporation and operated by its Buenavista del Cobre division. Grupo México is the third largest copper producer in the world and has a rail transport division, Ferrocarril Mexicano (Ferromex), that operates Mexico’s largest rail fleet. The Buenavista del Cobre mine, part-way through a $3.4 billion expansion plan, has some of the largest proven copper reserves in the world and is the world’s fourth largest copper mine.

The spill allowed 40,000 cubic meters of toxic copper sulfate acid to enter the Tinajas stream in the town of Cananea on 6 August 2014. Buenavista del Cobre claimed the spill was the result of an unforeseeable heavy rain storm, which triggered a rise in the level of water and copper sulfate in a holding tank being constructed at the copper mine. Grupo México has formed a team of 20 experts from the University of Arizona and Mexican universities to investigate the spill.

However, an initial report by the National Water Commission (Conagua) determined that the spill was caused by a flawed polyethylene pipe at one of the mine’s leachate tanks, together with a faulty valve at another tank. Conagua attributed the environmental disaster to negligence on the part of the company. Mexico’s federal environmental protection agency (Profepa) reported that the contaminants from the spill included copper, arsenic, aluminum, cadmium, chromium, iron, manganese and lead.

Mexico’s Environment Secretary Juan José Guerra Abud called it the “worst natural disaster provoked by the mining industry in the modern history of Mexico,” and confirmed that the spill contaminated not only the 17.6-kilometer-long (11-mile-long) Tinajas stream, but also the River Bacanuchi (64 kilometers in length), the River Sonora (190 kilometers long) and the El Molinito reservoir which stores 15.4 million cubic meters of water.

The contamination turned the waterways orange (see image) and affected the water supply of 24,000 people in seven communities along the rivers, forcing schools to close for several weeks while environmental authorities clean up the mess. More than 300 wells were shut down. The Sonora state government has been providing millions of liters of water via trucks to residents in the affected area. It has also started a temporary employment program to reactivate the local economy. The mining company has provided 13 million liters of water and $266,000 in immediate assistance to affected communities.

Some 800 mine workers, members of Mexico’s national mining and metallurgical workers union, blockaded the mine entrances in protest at the company’s failure to prevent the spill. Workers have been fighting over contracts since a strike in 2007.

The total clean-up costs are unknown, but likely to run into tens of millions of dollars.

On 18 August, Profepa filed a criminal complaint against Buenavista del Cobre and another Grupo México unit, Minera México, for their alleged roles in the spill. Grupo México could be fined up to 3.3 million dollars if the complaint is upheld.

Sonora State Governor Guillermo Padrés Elías has announced that the seven municipalities affected by the leached copper spill are filing a civil claim for damages.

Eight years ago in the northern state of Coahuila, an explosion in a coal mine belonging to Grupo México left 65 miners trapped underground; only two bodies were ever recovered.

In mid-August 2014, this significant fissure (see image) appeared near the city of Hermosillo in northern Mexico, with some press reports opting for headlines such as “The Earth Splits Open”:

fissure-hermosillo-eyewitness-news

While many press reports, especially those in English, tried to link this fissure to faulting and earthquake movements, others were more cautious, saying it was caused by movement of water underground followed by subsidence. Which version is correct? Probably neither is completely correct, since geography often fails to provide a single, definitive reason for things!

The crack is about 1000 meters (two thirds of a mile) long and up to 7 or 8 meters wide and 10 meters deep. While some press reports erroneously claimed that the crack extended across the main, paved, highway #26 between Hermosillo and the coast, its location was actually some distance away from the main highway. The road shown in the image above is a rural, unpaved road about 80 kilometers (50 miles) west of Hermosillo, in an area of farmland, some of which is irrigated.

Could the fissure have been formed by faulting associated with earth tremors or an earthquake? If this was the cause, the fence line, and the line taken by the road would have shifted position and no longer be straight. The image clearly shows that the road has been severed, but provides no evidence that the two sides have shifted position. Indeed, a close-up view confirms that even the existing fence remains in place:

fissure-hermosillo-fence-line

The available evidence therefore rules out faulting (or earth tremors or earthquakes) as the cause of the crack.

Could the fissure have been caused by an underground flow of water followed by subsidence (the collapse of overlying rocks)? This certainly looks more likely though it is hard to imagine significant underground flows of water in an area that is as flat as this. On the other hand, this is (a) an area of newly constructed irrigation ditches and ponds, and (b) it received heavy rainfall a few days before the crack was reported.

In all probability, the fissure began as a deep but very narrow “subsidence fissure” where differences in irrigation (or in water extraction) caused some parts to be much wetter than others. The soil and rock particles in wetter areas would tend to expand, while those in drier areas would tend to contract. Such differences could lead to the formation of small initial fissures.

Once the fissure had been started, localized heavy rains and the resulting overland flow could then result in streams flowing (temporarily) in these initial fissures. The moving stream water would rapidly widen and deepen the fissures into the scale of crack shown in the photos. The initial fissure may have been formed several years before this widening process occurred.

For a more detailed look at the evidence for this fissure’s formation (and its true location), see Debunked: The Earth Splitting Open – Giant Crack in Mexico.
